Back in his high school days, Joon-Seok (Joo Sang-Wook) was bullied by Chang-Sik (Yang Dong-Geun). Because of this, Joon-Seok’s high school days were like a nightmare. Now, Joon-Seok finds it difficult to live a normal life due to the bullying. Meanwhile, Chang-Sik, who has forgotten what he did to Jeon-Seok, lives a relatively happy life. He is about to marry Ji-Hee (Lee Tae-Im). Joon-Seok will pay him back for all the misery.

Romances end in blood and the frail hopes of individuals are torn apart in a vile karmic continuity of colonialism, civil war and occupation. After surviving Japanese colonization, Korea became the first war zone of the Cold War. The legacy of war remains today in this divided country. Three forlorn teenagers, Chank-guk, Jihum and Eunok are figures in the landscape of this story, which highlights the global implications of a very Korean reality. None of them is able to escape the withering pull of tragedy. All desperate pleas for love and redemption are returned stamped in red with “Address Unknown”.
